    x86-64 hardware

    I'm about to purchase 5 servers and will load OES Linux on all of them.
    I'm concerned about future use and expandability and such. Is there any
    reason to NOT buy a server with x86-64 (either Intel or AMD) to run OES
    on? Are there any issues I should know about?

    Sorry if this is in the wrong forum...I'm not sure where hardware stuff
    goes.

    Thanks.
    Steve

    In a few earlier posts it is being told that 64 bit isn't supported by SLES
    (which is OES).

    Cheers,

    That's true, but it doesn't prevent using AMD64 processors for OES.

    I recently installed an HP DL145G2 server with one dual core AMD64
    processor. This system works great and I am covered for any expansion
    possibilities. If I need to go to 64bit software later, I already have
    the dual core processor to handle it. If I need more processor then all
    I have to do is drop in another one. This machine is just coasting now
    so I expect I will have an empty processor slot for as long as it is in
    use, but it's there if needed.

    SLES is available (and supported) as 64bit, but the additional services
    that make up OES (eg NCP, NSS, eDir, iFolder etc) haven't been ported to
    64bit yet. So you run in 32 bit mode now, can upgrade to 64bit later.

    Hm..well, thats what I though as well so a few weeks ago I said that as an
    answer to a question but it supports AMD64 and the Intel EM64T architectures
    which is not *real* 64 bit I think.....

    Have a look at a post from 25-10-2005 with title "64bit?".

    I'm not 100% sure anymore now. Maybe you guys can shine a bit of light for
    me (us) here.

    Cheers,
    Edward

    They are real 64 bit processors.

    SLES can run as a full 64 bit implementation on 64 bit processor.
    OES, which is SLES + lots of extra services has to run in 32 bit, as the
    extra services have not been ported to 64 bit yet.

    So, SLES can be 32 or 64 bit. OES is 32 bit (for now anyway).

    Cool. Thanks guys! For the little bit of documentation I could find,
    that's what it appeared to be...SLES was 32 or 64...OES 32 only.

    I'm going 64bit

    Have a good holiday (for you US folks)!
